While interested parties continue to debate the definition of a Web 2.0 application, a Web 2.0 web-site may exhibit some basic characteristics. These might include:
"Network as platform" — delivering (and allowing users to use) applications entirely through a browser.[6] See also Web operating system.
Users owning the data on the site and exercising control over that data.[7][6]
An architecture of participation and democracy that encourages users to add value to the application as they use it.[6][1] This is a sharp contrast to hierarchical access control in applications, in which users are categorized into roles with varying levels of functionality.
A rich, interactive, user-friendly interface based on Ajax[6][1] or similar frameworks.
a Public good. "public goods" are characterized by two properties: jointness of supply and non-excludability (Hardin, 1982 [1]). The impossibility to exclude group members who didn’t contribute to the provision of goods from sharing its profits gives rise to the possibility that rational members will prefer to withhold their contribution of effort and free ride on the contribution of others (Marwell and Ames, 1979 [2]; Web 2.0 as Public Good [3]).
